यदि \(^{10}C_3=^{10}C_7\) है तो यह किस formula connection का उदाहरण है?
If \(^{10}C_3=^{10}C_7\), this is an example of which formula connection?
Explanation opens after your attempt
Correct Answer
C. \(^{n}C_r=^{n}C_{n-r}\)
Concept
This is the symmetry of choosing (r) and leaving (n-r). In exams use this relation when opposite indices sum to (n).
Why this answer is correct
The correct answer is C. \(^{n}C_r=^{n}C_{n-r}\). This is the symmetry of choosing (r) and leaving (n-r). In exams use this relation when opposite indices sum to (n).
Exam Tip
यह (r) चुनने और (n-r) छोड़ने की symmetry है। परीक्षा में opposite indices का sum (n) हो तो यह relation लगाएं।
